Oil change
Dear Friends,
When we buy fridge we do not change compressor oil for many years, But some one tell that we must change oil of compressor at for example R22 system after for example 500 operation hours.
Which one is true ?
Sincerely yours.Last edited by A.Mortezania; 01-03-2017 at 08:42 PM.
